The innovation doesnt matter. For something to have fundamental value, there has to be some mechanism by which that value can be realized.
With fiat currency, that mechanism is that I can easily and quickly exchange it for practically any service offered by pretty much anybody in the whole world, and that is backed by governments and large stable infrastructure.
All money is just a medium to exchange work between people, rather than a trade and barter economy which is inefficient.
Any current uses of bitcoin do not show it is a currency. I can probably convince a lot of people (especially in 3rd world countries) to accept things like cigarettes as payment. Heck, I could probably convince a lot of tradespeople to accept a car or some other valuable item in payment. None of these are ever going to be currency. Just like these, bitcoin lacks the fundamental advantages that were behind the adoption of money in the first place, so its extreme to suggest this is a realistic outcome.
As an asset, bitcoin has no tie to anything of tangible value. A stock is ownership of a portion of an operational company. You get a cut of all future profits. There is an anchor to some real world value. The reason google isnt worth 1c a share, is because you could buy the stock and receive a share of the profit. If the market suddenly went crazy, and drove google down to 1c for no reason at all and kept it there for the rest of time, its (hypothetically) no issue for you. You still receive the same % of profits and you laugh all the way to the bank.
Apply the same test to bitcoin. If the price went to 1c tomorrow and stayed their for the rest of time, how would you earn back your 19k usd per bitcoin? You couldnt.
And the commodity argument is even weaker - commodities trade because they have a use. Sugar, pork belly, wheat, oil etc. All have much more trade based on requirements of the underlying than speculation. These are staples of human activity. Suggesting bitcoin has any fundamental end use that outweighs speculation is just crazy.
